Both amps look interesting...especially the Seco Mojado...
Before you flip out too far on these though I would very strongly suggest searching out a Swart Atomic Space Tone (AST). I've played the first Duende a bunch - and the AST eats it alive in the overall tone dept. FWIW - it would stand to reason that Greg V, after working at Bogner, would be able to have any Bogner he wants, right? The AST is his go to rig - check these clips:
I thought the Seco Mojado looked like the best jam/open-mic/small-gig grab-and-go amp... I'd love to dual-lock my SE-70 into the back of it and just have it wired up all the time.
Funny, I just picked up a Duende combo. The early model with the Swamp switch. If you like the Shiva you will dig the Duende. The cleans wont be like the Swart, but you can get a great grinding rock sound going. Throw on a OD and shred away. Like this much better than the Lonestar Special(which was just missing a good crunch). The mixing of the 2 channels is way cool.
